Welp, since my original thread years ago my 08 RXTX has undergone some hidden changes.

Originally 255 hp and 70.1 mph, she now has a bunch more - somewhere north of 300. I'm still on the factory 1.5L block (forged) and supercharger. Head gasket and intercooler leaked a bit so it started a spiral (350 hours on the engine). I also finally got stopped by the cops for no annual registration sticker so I had to put that hideous thing on.

Original - 74.6 mph:
Gutted/shortened waterbox (muffler) with 3" thru hull exhaust
4" Kanaflex Intake with !flame arrestor
8400 rpm tune
1" exhaust manifold spacer
Speedreeks steering mount
Fiberglassed in OPAS blockoffs (off power assisted steering flaps held up by water pressure).
Sealed ride plate holes
R&D intake grate
Re-pitched prop

New - untested fully but should be flirting with 80mph:
Ported head (and painted valvecover)
Lightweight valves, springs, retainers
New MOTA intercooler (all copper/nickel/brass insides and diecast aluminum exterior)
New style OPAS blockoffs
Re-pitched prop
8800 rpm tune (in 2 weeks)
